A study has been made of the decay of a hydrogen plasma of ion density ~3���1015 cm?3 and temperature ~104�K. Details are presented of the experimental methods used to determine density and temperature distributions in the decaying plasma. The plasma decays by three-body recombination mainly and the experimental values of the recombination coefficient agree with those expected for a plasma opaque to Lyman radiation.

Spectral dynamics of femtosecond laser plasma induced on the sea water surface is investigated. Characteristic decay time of continuum and line intensity of Mg II, Ca II and Na I are determined. Electron density that changes from 3.0·1016to 2.4·1015cm-3was provided by usage of three-body recombination coefficient. It is shown that Na detection limit will be least in comparison with Mg and Ca.

AbstractAn ion embedded in warm/hot dense plasmas will greatly alter its microscopic structure and dynamics, as well as the macroscopic radiation transport properties of the plasmas, due to complicated many-body interactions with surrounding particles. Accurate theoretically modeling of such kind of quantum many-body interactions is essential but very challenging. In this work, we propose an atomic-state-dependent screening model for treating the plasmas with a wide range of temperatures and densities, in which the contributions of three-body recombination processes are included. We show that the electron distributions around an ion are strongly correlated with the ionic state studied due to the contributions of three-body recombination processes. The feasibility and validation of the proposed model are demonstrated by reproducing the experimental result of the line-shift of hot-dense plasmas as well as the classical molecular dynamic simulations of moderately coupled ultra-cold neutral plasmas. Our work opens a promising way to treat the screening effect of hot and warm dense plasma, which is a bottleneck of those extensive studies in high-energy-density physics, such as atomic processes in plasma, plasma spectra and radiation transport properties, among others.
